Close Alternative — 78.5% match
based on chemical composition and mechanical property overlap.
IS 3431 60Cr4V2 (IS 3431:1982) and BS 970 EN47 (BS 970:1955) are both steel grades.
Both fall under the Spring Steel category.
IS 3431 60Cr4V2 is typically used for volute, helical and laminated springs for automotive suspension; hot-rolled (also centreless ground or precision) bars and flats (clause 1.1), while BS 970 EN47 is commonly used for coil springs, leaf springs, torsion bars, valve springs, suspension springs, industrial springs requiring high fatigue life..
IS 3431 60Cr4V2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 EN47 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 3431 60Cr4V2 vs BS 970 EN47 is a 78.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 78.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
